这来自一个登录表单,其中电子邮件和密码作为 to 字段:
echo form_open('main/login_validation');
echo "<P>Email: </br>";
echo form_input('email',$this->input->post('email'));
echo "</P>";
echo "<P>Password: </br>";
echo form_password('password');
echo "</P>";
echo "<P>";
$img_path = base_url()."imgs/log_in_0.png";
echo '<input type="image" src="'.$img_path.'">';
echo "</P>";
echo form_close();
转到控制器进行表单验证:
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'Email', 'required|trim|xss_clean|callback_validate_credentials');
$this->form_validation->set_rules('password', 'Password', 'required|trim');
if($this->form_validation->run()){
$data = array(
'email' => $this->input->post('email'),
'is_logged_in' => 1
);
$this->session->set_userdata($data);
$nKey ='members';
$this->page($nKey);
} else {
$nKey ='login';
$this->page($nKey);
}
回调将其发送到:
public function validate_credentials(){
$this->load->model('model_users');
$salt = $this->model_users->get_salt();
if($this->model_users->can_log_in($salt)){
return true;
}else{
$this->form_validation->set_message('validate_credentials', 'Incorrect Email/Password.');
return false;
}
}
当它调用 get_salt() 时,它会从模型中加载:
public function get_salt(){
$this->db->where('email', $this->input->post('email'));
$query = $this->db->get('users');
if($query){
$row = $query->row();
$salt = $row->salt;
return $salt;
}else{
echo 'failed salt';
}
}
两天前同样的代码字很好,现在它给出了一个非对象错误:
$salt = $row->salt;
不会正确加载查询,我使用 codeigniter 从 post 数组function $this->input->post('email')
回显,它回显了正确的电子邮件。
但是当我print_r
查询时它返回一个空的查询对象,但是电子邮件在用户数据库表中(在电子邮件字段和所有内容中),我已经检查过了,几天前我正在使用同一个帐户进行测试
